Question

the area of a circle is 113.04. what is the radius of the circle? (use 3.14 for pi) (only type the number, no words or symbols)

Explanation:

Step1: Recall area formula

The area formula of a circle is $A = \pi r^{2}$, where $A$ is the area and $r$ is the radius.

Step2: Substitute given values

We know $A = 113.04$ and $\pi=3.14$. So, $113.04 = 3.14r^{2}$.

Step3: Solve for $r^{2}$

Divide both sides of the equation by 3.14: $r^{2}=\frac{113.04}{3.14}=36$.

Step4: Solve for $r$

Take the square - root of both sides. Since $r>0$ (radius is a non - negative quantity), $r = \sqrt{36}=6$.
